CHC Navigation (CHCNAV), a global provider of geospatial and machine control technologies, announced its participation in the 8th International Construction and Survey Productivity Improvement Expo (CSPI-EXPO 2026), held June 17 to 20, 2026, at Makuhari Messe in Chiba, Japan.
At Booth 12-61, CHC Navigation will present integrated solutions for construction, surveying, mapping, and marine operations. Visitors can meet the CHCNAV team, review application workflows, and see how connected field technologies help improve productivity and data quality across real-world jobsite conditions.
The CHCNAV AlphaAir 6 (AA6) is designed for efficient aerial surveying in complex and high-relief terrain. It combines prism-based scanning with a high-grade inertial navigation system to support long-range measurements up to 2,100 m and typical operating altitudes of 100 to 600 m AGL. Real-time waveform processing supports improved point cloud density and data completeness, while open interfaces help enable integration with multirotor and fixed-wing UAV platforms.
The CHCNAV RS7 is a tool-grade handheld LiDAR SLAM scanner designed for building and interior applications. By combining high-precision INS and SLAM, it supports stable motion tracking in feature-poor environments. With 1.15 million points per second, a 360° x 189° field of view, HD imaging, 3D Gaussian Splatting (3DGS), and device-to-cloud workflows, RS7 supports efficient reality capture and faster deliverables.
The CHCNAV APACHE 4 Pro is a compact USV platform designed for hydrological survey tasks. It supports integration with mainstream ADCPs and can be configured with the CHCNAV HQ-400 multibeam echo sounder for bathymetric surveys. The platform can also be adapted to carry additional sensors such as water quality meters and side-scan sonar, depending on project requirements.
The CHCNAV TX73 system supports excavator guidance by providing real-time bucket position relative to digital design models. With a high-precision GNSS receiver and IMU sensors, it helps operators reach target surfaces more efficiently and reduce reliance on staking, supporting improved speed, quality, and repeatability on earthmoving projects.
The CHCNAV ViLi i100 is a flagship GNSS RTK receiver designed for high-precision surveying in challenging environments. With SFix 2.0 positioning, advanced GNSS filtering, and integrated Vi-LiDAR technology, it supports reliable centimeter-level accuracy beyond traditional GNSS limits.
CSPI-EXPO is a major exhibition focused on improving productivity in construction and surveying. The 2026 edition will be held June 17 to 20 at Makuhari Messe in Chiba, Japan. Learn more at https://cspi-expo.com/
